Systems and methods for reporting random access information in wireless communication networks

Abstract

Systems and methods for storing and transmitting random access (RA) information related to one or more RA procedures is discussed herein. In one embodiment, the systems and methods are configured to storing, by a wireless communication device, RA information of multiple sets of RA resource of a completed RA procedure. The method further includes receiving, by the wireless communication device from a wireless communication node, an indicator via a radio resource control (RRC) message. The method also includes transmitting, by the wireless communication device to the wireless communication node, responsive to the indicator, the RA information of the multiple sets of RA resource of the completed RA procedure.

         2 . The method of  claim 1 , wherein each RA attempt of the completed RA procedure utilized one of the multiple sets of RA resources. 
     
     
         3 . The method of  claim 1 , wherein the RA information includes a resource set identifier. 
     
     
         4 . The method of  claim 1 , wherein the RA information includes a starting frequency of a physical random access channel (PRACH). 
     
     
         5 . The method of  claim 1 , wherein the RA information includes a number of physical random access channel (PRACH) transmission occasions frequency-division multiplexed at a time instance. 
     
     
         6 . The method of  claim 1 , wherein the RA information includes a subcarrier spacing of a physical random access channel (PRACH). 
     
     
         7 . The method of  claim 1 , wherein the RA information includes at least one of: a physical random access channel (PRACH) index, a power ramping step for a PRACH, a backoff indicator, a resource type, or a RA prioritized parameter. 
     
     
         8 . The method of  claim 7 , wherein the resource type identifies a set of RA resources being used for a RA attempt. 
     
     
         9 . The method of  claim 1 , further comprising transmitting, by the wireless communication device to the wireless communication node, the one or more sets of RA information via at least one information element. 
     
     
         10 . The method of  claim 1 , wherein the RA information includes an index of a set of RA resources utilized in a successive RA attempt in a same beam. 
     
     
         11 . The method of  claim 1 , further comprising transmitting, by the wireless communication device to the wireless communication node, responsive to the indicator, an indication of a preamble group associated with the completed RA procedure. 
     
     
         12 . The method of  claim 11 , wherein the indication indicates whether a preamble used in an RA attempt is selected from a specific preamble group. 
     
     
         13 . The method of  claim 11 , wherein presence of the indication transmitted to the wireless communication node indicates that a preamble used in an RA attempt is selected from a specific preamble group, and absence of the indication indicates that the preamble used in the RA attempt is not selected from the specific preamble group. 
     
     
         14 . The method of  claim 11 , wherein absence of the indication indicates that a preamble used in an RA attempt is selected from a predefined preamble group. 
     
     
         15 . The method of  claim 1 , further comprising transmitting, by the wireless communication device to the wireless communication node, responsive to the indicator, time-related information of the completed RA procedure. 
     
     
         16 . The method of  claim 15 , wherein the time-related information is indicative of a time the completed RA procedure is initiated or completed. 
     
     
         17 . The method of  claim 15 , wherein the time-related information is indicative of a time duration for the completed RA procedure. 
     
     
         18 . A method, comprising:
 transmitting, by a wireless communication node to a wireless communication device, an indicator via a radio resource control (RRC) message; and   receiving, by the wireless communication node from the wireless communication device, one or more sets of random access (RA) information, each RA information of the one or more sets of RA information corresponding to respective different RA procedures, wherein at least one RA information of the one or more sets of RA information corresponds to a respective completed RA procedure and includes multiple sets of RA resources of the completed RA procedure, after the indicator is transmitted.   
     
     
         19 . A wireless communication device, comprising: 
       at least one processor configured to:
 store one or more sets of random access (RA) information, each RA information of the one or more sets of RA information corresponding to respective different RA procedures, wherein at least one RA information of the one or more sets of RA information corresponds to a respective completed RA procedure and includes multiple sets of RA resources of the completed RA procedure; 
 receive, via a transceiver from a wireless communication node, an indicator via a radio resource control (RRC) message; and 
 transmit, via the transceiver to the wireless communication node, responsive to the indicator, the one or more sets of RA information. 
 
     
     
         20 . A wireless communication node, comprising: 
       at least one processor configured to:
 transmit, via a transceiver to a wireless communication device, an indicator via a radio resource control (RRC) message; and
